Yes, I haven't had much fun since hitting 100 I must say, there's quite a bit to do but none of it particlularly appealing. I disagree about it being the weakest expansion though. It's not in the same class as MOP but it trounces Cata into the ground for me.
I doubt i'll be on much once the final version of Elite Dangerous comes out on Dec 16th. I only have time for one MMO at a time and i'll be opting for the one i've been waiting nearly 30 years for.
